I would add that having a cursory understanding of marketing, and more importantly how to market yourself is factor as well. Simply being popular and attractive isn't really enough on it's own. OF is full of very attractive women who make almost no money even if they make fully explicit content. The girl needs to have understanding of what kind of audience she has or wants, and how best to market herself to that audience. This includes understanding the changing nature of the algorithm and how it affects her marketability. You can see this in effect with the girls who completely switch up their content, yet keep their OF open. Shae seems to have a good understanding of her own marketability.
